Additional file 2 of Magma mass increase under Sakurajima Volcano, Japan, inferred from campaign relative gravity and leveling data from 1975 to 1992: an interpretation from volcanic gas studies

Additional file 2: List of the vertical deformation rate at the leveling points ( $$u_{\text{obs}}$$ u obs ; red arrows in Fig. 2b, c), determined from the campaign leveling data obtained from March 1975 to December 1991. This CSV file consists of eight columns: the name of the leveling point, longitude, latitude, elevation, vertical deformation rate, standard deviation of the vertical deformation rate, the name of the referenced leveling point, and note.
